Unreal Engine 4 game VS integrated video card

Hello. One guy (who played my game) said that he get “Out of VRAM error” when starting a game. He have old (but not very old) notebook with a integrated video card. A game uses only 300 MB VRAM, and his PC are fine for low settings. Unreal Engine 4 dont likes only old integrated video cards, or every one? And can I somehow change it?
